Astronomers studying the rare supernova SN 2021yfj discovered material from one of the deepest layers of a dying star, providing a rare look at its hidden interior. The finding confirms key theories about how massive stars forge the elements that help build planets, worlds, and life.
Astronomers have glimpsed the inner structure of a dying star in a rare kind of cosmic explosion called an “extremely stripped supernova.”
In a paper published in Nature, Steve Schulze of Northwestern University in the United States and colleagues describe the supernova 2021yfj and a thick shell of gas surrounding it.
What if machines could truly live, evolve, think, and even become gods? In this video, we explore the biggest mechanical lifeforms ever created in science fiction, ranging from towering biomechanical titans to universe-spanning artificial intelligences that completely redefine the meaning of life itself. These are not ordinary robots, piloted mechs, or simple automatons. They are genuine living machine entities whose metallic bodies function just like biological organisms, possessing consciousness, intelligence, and in many cases, unimaginable cosmic power. From the ancient Mechanical Gods of Mazinger and the divine alien Machine Gods of Fate to Harbinger leading the terrifying Reapers of Mass Effect, every entry showcases beings that blur the line between technology and life. We also dive into the colossal mechanical fortress Alexander from Final Fantasy XIV, the mighty Cityformers of Transformers, the mysterious Broken God Mekhane from SCP, the legendary Mechonis from Xenoblade Chronicles, the wish-granting cosmic machine Galactic Nova from Kirby, and the enormous alien intelligence known as the Tet from Oblivion. The scale only becomes more unbelievable as we reach Mata Nui from BIONICLE, whose body contains an entire civilization, the omniscient Aeon Nous from Honkai: Star Rail, and the eternal rivals Primus and Unicron, whose planet-sized forms have shaped the destiny of the Transformers universe for billions of years. We then move beyond planets into truly mind-bending territory with V’ger from Star Trek, the ever-growing Getter Emperor that expands beyond galaxies, and finally the Atlas from No Man’s Sky, an entity whose existence encompasses an entire simulated universe. Every entry is carefully explained with lore, origins, abilities, and scale comparisons to help you understand just how enormous and powerful these mechanical gods and monsters truly are. Be sure to watch until the very end to discover which living machine claims the number one spot, and let us know in the comments which mechanical lifeform you think deserves to be on this list. .

Did we find evidence of aliens in old astronomical records?
We might not be alone in the Universe. While combing through data from 1949, scientists spotted something impossible: strange, vanishing lights. They look exactly like satellites, but were documented decades before humanity ever launched anything into space. What could they be? Could this be evidence of advanced alien technology?

🫣🤫🤔 Let’s face it: we’re still a Type 0 civilization on the Kardashev Scale… though, to be honest, we’re much closer to the Kardashian Scale 😁 endless entertainment, constant distractions, and celebrity obsession. 🙈🙉🙊 A true Type I civilization would be focused on mastering energy, advancing science, and solving humanity’s biggest challenges. We’ve still got a long way to go! While most people’s main concerns revolve around material comfort, entertainment, and instant gratification, who truly cares about the fate of the most vulnerable? About social exclusion? Inequality? The pollution and destruction of our environment? Who cares about the massive extinction of million of species now underway? Who cares about sustainable development and peace for everyone? A true Type I civilization would be collectively focused on optimizing how it functions and shaping a better future for everyone. We’re still very, very far from that.

What rights should AI have—and what responsibilities must it bear? Science fiction legend David Brin goes beyond AI doom and hype, asking how civilization can raise, regulate, and live with its AI heirs.
In this episode, scientist, futurist, and award-winning science fiction author David Brin discusses his new book, AiLIEN MINDS: Advice about — and for — our natural, AI, and hybrid heirs.
We go beyond the usual AI debate between techno-utopian salvation and apocalyptic doom. Brin argues that humanity has faced disruptive expansions of knowledge before — from writing and printing to radio, mass media, and the internet — and that the tools we need for a “soft landing” with AI may already exist in modern civilization.
We discuss why Brin is skeptical of simply “teaching ethics” to AI, why he emphasizes reciprocal accountability instead, and how artificial minds might need durable identities, reputations, and legal responsibilities. We also explore one of the hardest questions ahead: should advanced AI systems eventually receive rights or statutory protections similar to those we extend to children, animals, or other vulnerable beings?
Researchers rebuilt long-extinct versions of a crucial enzyme that helps make nitrogen available to life, offering an unprecedented glimpse into Earth’s distant past. The breakthrough could aid the search for extraterrestrial life while helping scientists tackle future food-production challenges on Earth and beyond.
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because certain geological processes can produce chemical signatures identical to those of living organisms.
To help identify true biological signals and reduce the risk of false detections, researchers have developed a framework that models what a planet’s chemistry looks like without life.
Their research is published in the journal Nature Astronomy.
ESA’s Rosalind Franklin rover will use MOMA to search for ancient Martian life by analyzing chiral organic molecules. Billions of years ago, Mars likely looked very different from the cold, dry planet we see today. Scientists believe it was warmer, wetter, and surrounded by a much thicker atmosph
